Mosquito Populations in Plano

Traps set up within the City in the last 10 ears have yielded samples of Culex spp. mosquitoes, which are capable of carrying WVN.  Likelihood of WNV generally increases during summer months as Culex spp. mosquito populations increase.  These mosquitoes thrive in hot weather and may become infected after biting a bird with WNV.

Help Prevent the Spread of WNV
Aside from being vigilant in prevention of mosquito bites, the best prevention against any mosquito-borne disease is to implement appropriate measures to reduce the mosquito population. Mosquitoes need standing water to lay their eggs, producing adults in just ten days in hot temperatures


The most effective methods to control presence of mosquitoes is to remember the four D’s:
  • Dusk / Dawn are times of day you should try to stay indoors. This is when mosquitoes are most active.
  • Dress in long sleeves and pants when outside to keep skin covered. For extra protection, spray clothing with repellent.
  • DEET is a desirable ingredient in insect repellents. Follow label instructions and always wear repellent when outdoors.
  • Drain standing water in your yard and neighborhood-old tires, flower pots, rain gutters, bird baths, etc. Keep swimming pools treated and circulated, and rain gutters unclogged. These are common mosquito breeding sites.
Steps Being Taken by the City of Plano 
In addition to these precautions, the Environmental Health Department has begun identifying low-flow creeks within the city. As sites are identified, work will be conducted to improve flow and reduce mosquito populations in these areas. Another effective measure utilized by the Department will be application of approved larvicide in identified mosquito breeding areas. 

Finally, sections of the City will be sprayed with EPA-approved adulticide. Citizens should be aware spraying is only one component of an Integrated Mosquito Management Program used to.control presence of mosquitoes. Download a
